United Airlines is testing out a new feature that will allow flyers to scan their passports on their mobile phones to check in for international flights.
The airline is the first US carrier to launched the new service, which works with its mobile app and can be accessed 24 hours before flight departure.
After initiating the app's check-in feature, customers can scan their passport using their mobile device's camera to capture photos of the documents.
The technology works in the same way as mobile banking services that allow consumers to deposit a check without having to visit the bank. After taking photos of the front and back of the endorsed check, customers simply select the deposit account, and submit the images.
Likewise, at United, once a credentials management company has verified the passport, customers will receive their boarding pass.
The carrier, which was also the first US airline to introduce mobile boarding passes in 2007, will collect feedback during the testing phase before launching it systemwide.
